The growing threat of an NBA lockout hasn’t yet scared off many season-ticket buyers, as the league enters June with a season-ticket renewal rate ranging between 75 percent and 80 percent. That renewal rate comes on the heels of the league setting a full-season-ticket sales record last year.

NBA Deputy Commissioner Adam Silver said prior to Game 1 of the Finals in Miami that the league’s season-ticket refund policy to be offered in the event of a lockout has helped maintain its renewal business.

“We are not surprised (by the renewal rate),” he said.

The NBA is promising full refunds plus interest to season-ticket holders for any games lost to a lockout.

Chris Granger, NBA executive vice president of team marketing and business operations, said one-third of the league’s 30 teams already have sold at least 1,000 new full-season tickets, including the Memphis Grizzlies, Los Angeles Clippers and Washington Wizards.

“The pacing is as strong as we have ever seen at this point in the year,” Granger said. “They are not the usual suspects.”

League executives said they are not yet expecting a major drop in season-ticket sales leading up to a potential work stoppage.

“People are still entranced with the stellar playoffs,” Granger said. “We will continue to sell during the coming weeks and months.”

Despite the strong season-ticket renewal rate, Silver said the NBA is feeling some damage from the looming lockout in other areas.

“We haven’t felt a season-ticket impact, but it is bad for business,” he said. “Our marketing partners run summer campaigns and buy media in advance, so the uncertainty already has had an impact.”
